I don't see advantages in propretary protocols as of Skype. I just think I see the importance (as often found) that free software "has to" play nice with the proprietary ones, the established ones. Because users often require the free software to be "like" the proprietary one, this is one of the reasons that might make then switch. Often, it's not just about pure functionality (which, by the way, is the requirement to be met for anything to work properly), but it's also the usage share (cf. "market share") of a certain product, technology, protocol or program. However, working SIP telephony programs for FreeBSD would enable the system to do lots of magic things, especially in combination with let's say Asterisk PBX. There is lots of potential in it, and it will be more and more important in the future. > What we need though, that's a WORKING and robust NAT traversal > technique, be it in Ekiga or any other SIP-based softphone.
